Team Members: • Carrie Hawkins • Kendal Hathaway • Mandie Manning • Tyler Merrill
Project Overview • Why we did project • What is involved • equipment • equations • programming
Radiation • Harmful to environment • Measurement (CPM and Nanocuries)
Cosmic radiation is high-energy gamma radiation that originates in outer space and filters through our atmosphere. Sea Level -- 26(Increases about 1/2 mrem for each additional 100 feet in elevation) Atlanta, Georgia -- 31 (1,050 feet) Denver, Colorado -- 50 (5,300 feet) Minneapolis, Minnesota -- 30 (815 feet) Salt Lake City, Utah -- 46 (4,400 feet) Cosmic Radiation(MEASURED IN MREM/YEAR)
United States (avg.) -- 26 Denver, Colorado -- 63 Nile Delta, Egypt -- 350 Paris, France -- 350 Coast of Kerala, India -- 400 McAipe, Brazil -- 2,558 Pacos De Caldas, Brazil -7,000 Terrestrial sources are naturally radioactive elements in the soil and water such as uranium, radium,and thorium. Average levels of these elements are 1 pCi/gram of soil. Terrestrial Sources(MEASURED IN MREM/YEAR)
GPS UNIT • What is it? (Geographical Positioning System) • How does it work? • How is it involved in our project?
GPS Satellite • History • when was it invented • use today
Interpolation • Definition • C++ program • Sample
Sample: f(b) - f(a) f(c) - f(a) ------------- = ------------- b - a c - a
C++ Program • cout<<"Input point you want to know(x1): "; • cin>>x1; • cout<<"Input point you want to know(x2): "; • cin>>x2; • cout<<"Input point you want to know(x1): "; • cin>>x1; • cout<<"Input point you want to know(x2): "; • cin>>x2;
C++ Program (cont.) if ((x1>=a1)&&(x2>=a2)&&(x1<=b1)&&(x2<=b2)) { w=a3-b3;//difference radiation content y=b1-a1;//run larger z=b2-a2;//rise larger m=sqrt((y*y)+(z*z));//slope larger y1=x1-a1;//run smaller z1=x2=a2;//rise smaller m1=sqrt((y1*y1)+(z1*z1));//slope smaller result=((w*m1)-(a3*m))/-m; cout<<"The result is: "<<result<<endl; }
Gathering Data • GPS unit • Average radiation content
